VENTILATING SASH-LJOCK.

SPECIFICATION forming part of Letters Patent No. 769,012, dated August 30, 1904.

Application liled April l1, 1903. Renewed May 6, 1904. SeriaINo. 206,642. (No model.)

To {v7/Z whom, it 77mg/ concern:

Be it known that I, VVILLARD N. PACKER, a citizen ofthe United States, residing at Shelby, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Ventilating Sash-Locks, of which the following is a specification.

This invention relates to Window-buttons of the type providing means for locking orvfastening together themeeting-rails of windowsashes; and it has for its object to provide an improved sash-lock of this characterwhich may be properly termed a Ventilating' sashlock, as the same comprises means for securely locking the sashes together either in a closed position or when partially opened for the purposes of ventilation by permitting the window to be partly open at top or bottom or both at top and bottom and still be secure against opening from unauthorized agencies outside of the window.

To this end the invention contemplates a simple and practical type of sash-lock embodying a minimum number of working elements, while at the same time providingasecure lock under any conditions indicated and at the same time not interfering with the complete opening of either or both sashes whenever this is desired.

Another object of the invention is to provide a sash-lock construction the several parts of which` may be made from stampings in a simple and practical manner.

With these and many other objects in view, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts, which will hereinafter be more fully described, illustrated, and claimed.

The essential features of the invention involved in the novel manner of separably interlocking the separate members of the lock to permit of the Various adjustments of the sashes are necessarily susceptible to modification from a structural standpoint without departing from the scope of the invention;

Abut a preferable embodiment thereof is shown in the accompanying drawings, in which- Figure-1 is a perspective view of a sash-lock constructed in accordance with this invention and shown in position for holding the meeting-rails locked together when both sashes are closed. Fig. 2 is avertical sectional view of the lock with the parts in the relation shown in Fig. l. with the parts shown in the relation which they occupy when either or both sashes are partly open for Ventilating purposes. Fig. L is a similar view showing the separable interlocking members separated to permit of the complete opening of either sash. Fig. 5 is a rear perspective view showing the arrangement of parts illustrated in Fig. 3. Fig. 6 is a perspective view of the complete sashlock device, showing the members and constituent elements separated.

Like reference characters designate corresponding parts throughout the several figures of the drawings.

The complete sash-lock device constructed in any suitable manner and of any suitable material as an entirety consists of two separate members A and B, carried, respectively, by the separate meeting-rails of the upper and lower sashes. Vhile the separate members could be respectively arrangedA on either of the meeting-rails, still the preferable and practical arrangement, as shown in the drawings, consists in applying the member A to the meeting-rail of the llower sash L and the member B to the meeting-rail of the upper sash U of the window. So for convenience in understanding the action of the lock the arrangement illustrated will be speciiically referred to. The sash-lock member A, which is fastened to the upper face of the meetingrail of the lower sash L, essentially comprises a base-plate l and a vertically-rocking fastening-lever element 2, mounted thereon.

base-plate l is of a iattened form to rest iiat upon the rail to which it is attached and is preferably provided at the under side thereof with a retaining lug or projection 8,-titting in Fig. 3 is a similar view The a correspondingly shaped and sized mortisec in the meeting-rail to provide for firmly interlocking the member A with the said meeting-rail and holding' the same against creeping' or displacement incident to any heavy strain or pressurcimj'iosed thereon. In addition to the retaining' lug` or projection 3 the said base-plate 1 is fui'ther provided with the perforated fastener ears receiving' the sci'ews or other fasteners to secure the plate to the rail, and at its inner edg'e the plate 5 overhang's the adjacent edge of the rail to produce an overhanging' guard-lip 6, which spans the joint between the meetingrails when closed and effectually 'prevents the introdiiction of a knife or other instrument from the outside between the meeting' sash-rails. In conjunction with the overhang'ing' g'uard-lip 6 the said base-plate 1 is also provided, at the inner corners thereof, with the upstanding auxiliary guai'd-ears 7 of a shouldered formation to also bridge the joint between the meeting-rails and prevent the introduction of an instrument laterally beneath the latch or coupling element 8 of the member B, to be presently referred to.

' The rocking fastening-level' element 2 is mounted at a point intermediate its ends upon a horizontal pivot 9, passing' therethrough and also through a pair of upstanding bearing'- ears 10, arising' from the base-plate 1 and between which tlie lever 2 is supported This levei' is of peculiar formation to provide for fastening or locking the two sashes either in closed or partially open positions. At one side of its horizontal pivotal support 9 the lever is formed with a substantially straight coiipling-arm 11, provided at its terminal with a T-head 12, producing' oppositely-projecting holding-lugs. This T-head 12 and the holding-lugs, constituting' a pai't thereof, are preferably formed by slitting the inner end of the arm 11 a short distance, as at 13, and bending the portions at opposite sides of the slit. respectively, to opposite sides of the arm. thereby forming the lugs or head which serve to hold the two members of the sash-lock separably interlocked in the mannei' illustrated in the drawings. At the other side of its pivot the fastening-lever element 2 is formed with a vertically arched or curved catch-arm 14 substantially in the foi'm of a hook and provided at its terminal with a shouldered locking-tip 15, having a play within the clearance-notch 16 at the outer end of the base-plate 1 and adapted to have a snapping engagement with the swinging end of the latch or coupling element S of the lock member B. In connection with the construction of the fastening-levei' element 2 it is also to be observed that the separate ai'm meinbers 11 and 14 of the lever are angularly related and disposed in planes substantially oblique to each other to permit of the 4saine the fastening-lever 2.

assumingthe positions plainly shown, respectively, in Figs. 2 and 3 of the drawings.

Referring moi'e particularly to the construction of the lock member B, it is to be observed that the latch or coupling element 8 is in the form of a vertically-swinging' slotted link of an oblong' form and usually constructed with a reinforcingrib 17 about the' edge thereof. In addition to the rib 17 the latch element 8 is provided with a web portion 18, having a T-sliaped slot consisting of a longitudinal section 19, extending substantially the fulllength of the latch, and a ci'oss-slot 20 in communication with the slot-section 19 and at the extreme inner end thereof, said crossslot 20 forming oppositely-located clearancenotches for the oppositely-projecting holding'- lugs 12 of the coiipling-arm 11, as will hei'einaftei' appeai'. At the inner end thereof the latch element 8 is formed with a cylindrical pivot-bar member 21, having a flattened side portion 22 and terminal pivots 23 turning in the oppositely-located pivot-ears 241, stamped up fi'om an attaching or base plate 25, which is secured to the upper face of the meeting- `rail of the upper sash U. The attachingplate 25 is also formed with perforated fastener-ears 26 for the screws or other fasteners and at an intermediate point with the integral curved pressure-tongue 27, bent forwardly over the pivot-bar member 21 and adapted to have a spi'ing or friction pressure thereon and also to have a holding' engagement with the flattened side portion 22 of the said pivot-bai' 21 when the latch is in its horizontal position over the fastening-lever element 2, as plainly shown in Fig'. 2 of the drawings.

T ith the meeting-rails in their matching,

closed positions both sashes are locked against opening by moving' the slotted latch or link S downward over the fastening-lever 2, so that the outer end edge of the longitudinal slot 19 may be forced into snapping engagement with the shouldered locking-tip 15 of In this position of pai'ts the lever 2 projects upwardly through the slot 19,and the pressui'e-tongue 27 assists in holding the latch in its locked position by engagement with the flattened side portion 22. If it is desired to arrange the parts so as to provide for a separation of the meeting-rails with a partial opening ofleither or both of the sashes at their other ends, the free end of the latch 8 is di'awn up, thereby rockingthe fastening-lever on its pivot to a position which permits of the ready disengagement of the latch from the tip 15 of the lever. Then it is only necessary to move the upper sash downward or'the lower sash upward to slidablyy carry the coupled parts to the position shown in Figs. 3 and 5 of the drawings. In this movement, since the T-head 12 of the coupling-ai'm 11 moves through the longitudinal slot-section 19 towai'd the unpivoted'end of IOO IIO

`thc latch, it is impossible forA the elements to become separated, and they consequently remain slidably interlocked or coupled in any and all positions. 'When the meeting-rails are brought together again, the parts are locked by being moved to the positions shown in Fig. 2, as already explained, and in thehorizontal locked position of the latch 8 the same lies flat upon the plate l between theopposite auxiliary guard-ears 7 thereof. I

Should it be desired to uncouple or separate the members A and B to permit of the complete opening of either of the sashes at the time of raising the free end of the latch to disengage it from the catch-arm 14 of the leven-the inner coupling-arm l1 of such lever is held down by the finger to permit the T-head 12 to remain in theplaneof the clearance slot-section 20 until the latch 8 has been raised entirely over the said T-head to the position shown in Fig. 4 and in which position the two members are entirely uncoupled for the purpose indicated.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described Ventilating sash-lock Will be readily apparent Without further description, and it Will also be understood that changes in the form, proportion, and minor details of construction may be resorted to Without departing from the spirit of the invention or sacriiicing any of the advantages thereof.
